Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Policies	Basis of Presentation and Significant Policies Basis of Presentation The unaudited condensed consolidated financial statements included in this Form 10-Q have been prepared in accordance with the U.S. Securities and Exchange Commission (the “SEC”) instructions for Quarterly Reports on Form 10-Q. Accordingly, the condensed consolidated financial statements are unaudited and do not contain all the information required by U.S. Generally Accepted Accounting Principles (“GAAP”) to be included in a full set of financial statements. The unaudited condensed Consolidated Balance Sheet at December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for a complete set of financial statements. The audited consolidated financial statements for our fiscal year ended December 31, 2023, filed with the SEC on Form 10-K on March 22, 2024, include a summary of our significant accounting policies and should be read in conjunction with this Form 10-Q. In the opinion of management, all material adjustments necessary to present fairly the results of operations, cash flows, and balance sheets for such periods have been included in this Form 10-Q. All such adjustments related to continuing operations are of a normal recurring nature. The results of operations for interim periods are not necessarily indicative of the results of continuing operations for the entire year. On May 17, 2024, the Company entered into an Asset Purchase Agreement with Timber Technologies Inc. and Timber Properties, LLC ( collectively, “TT”) (see Note 12. “Mergers and Acquisitions”). On June 12, 2024, the Company executed a one-for-five reverse stock split which became effective June 14, 2024. All of the Company’s historical share and per share information related to issued and outstanding common stock and outstanding options and warrants exercisable for common stock in these financial statements have been adjusted retroactively (see Note 15. “Equity Transactions”). The Company Star Equity Holdings, Inc. (“Star Equity,” the “Company,” “we,” or “our”) is a multi-industry diversified holding company with two divisions: Building Solutions (formerly known as Construction) and Investments. Our common stock and preferred stock are listed on the NASDAQ Global Market exchange as “STRR” and “STRRP,” respectively. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, asset impairment, business combination accounting, and income taxes. Actual results could materially differ from those estimates. Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions or in major money market mutual funds offered through brokerage firms. Some of our cash balances are maintained at major banking institutions in the United States, a portion of which may, from time to time, exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. As of June 30, 2024, we had $0.7 million of cash in excess of FDIC insured limits. New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2024 that are expected to have a material impact on our financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations On May 4, 2023, we entered into a Stock Purchase and Contribution Agreement (the “Purchase Agreement”), by and among the Company, Digirad Health Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Digirad Health”), TTG Imaging Solutions, LLC, a Pennsylvania limited liability company (“TTG”), and TTG’s parent, Insignia TTG Parent LLC, a Delaware limited liability company (the “Parent”). Pursuant to the Purchase Agreement, (i) TTG purchased 85% of the issued and outstanding shares of Digirad Health, on the terms and subject to the conditions set forth therein and (ii) the Company contributed to Parent 15% of the issued and outstanding shares of stock of Digirad Health (the “Contributed Shares”) in exchange for New Units (as defined in the Purchase Agreement) of Parent (the “TTG Transaction”). The total aggregate consideration payable to the Company for the TTG Transaction was $40 million, comprised of $19.7 million ($27 million less payoff of debt to Webster Bank (see Note 8. “Debt”) and transaction costs) in cash, a $7 million promissory note (see Note 5. “Supplementary Balance Sheet Information”), and $6 million of New Units in the Parent (see Note 5. “Supplementary Balance Sheet Information”). The Company completed the sale of Digirad Health simultaneously with entering into the Purchase Agreement. We deemed the disposition of Digirad Health, which operated our Healthcare business unit, to represent a strategic shift that had a major effect on our operations and financial results. As of the date of these financial statements, the results of operations of the Healthcare business unit represent “discontinued operations” in accordance with GAAP (ASC 205-20-45-1B). As such, the assets and liabilities, as well as the earnings, of the discontinued operation are presented separately in the unaudited condensed consolidated financial statements, as applicable, for all periods presented. Unless otherwise noted, discussion within the notes to the unaudited condensed consolidated financial statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations relates to continuing operations. Our variable interest entity (“VIE”), for which we were not the primary beneficiary, was disposed of as part of the sale of our Healthcare division. This VIE was in a small private company that is primarily involved in research related to new heart imaging technologies. The following table presents financial results of our Healthcare division for the three and six months ended June 30, 2024 and 2023 (in thousands).

Earnings Per Share [Abstract]
Basic and Diluted Net Income (Loss) Per Share	Basic and Diluted Net Income (Loss) Per Share We present net income (loss) per share attributable to common stockholders in conformity with the two-class method required for participating securities, as the warrants are considered participating securities. We have not allocated net income (loss) attributable to common stockholders to warrants because the holders of our warrants are not contractually obligated to share in our income (loss). Basic net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share attributable to common stockholders is calculated to give effect to all potential shares of common stock, including common stock issuable upon exercise of warrants, stock options, and restricted stock units (“RSUs”). In periods for which there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive. All share amounts reflect 1 for 5 reverse stock split effective June 14, 2024, retroactively The following table sets forth the reconciliation of shares used to compute basic and diluted net income (loss) per share for the periods indicated (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Numerator: Income (loss) from continuing operations, net of tax $ (3,787) $ (1,366) $ (6,011) $ (1,350) Income (loss) from discontinued operations, net of tax (Note 2) — 26,957 — 27,376 Net income (loss) (3,787) 25,591 (6,011) 26,026 Dividend on Series A perpetual preferred stock (479) (479) (958) (958) Net income (loss) attributable to common shareholders $ (4,266) $ 25,112 $ (6,969) $ 25,068 Denominator: Weighted average common shares outstanding 3,172 3,039 3,170 3,039 Weighted average prefunded warrants outstanding — 65 — 65 Weighted average shares outstanding - basic 3,172 3,104 3,170 3,104 Net income (loss) per share Continuing operations Basic and diluted $ (1.19) $ (0.44) $ (1.90) $ (0.43) Discontinued operations Basic and diluted $ — $ 8.68 $ — $ 8.82 Net income (loss) per share Basic and diluted $ (1.19) $ 8.24 $ (1.90) $ 8.38 Net income (loss) per share, attributable to common shareholders Basic and diluted $ (1.34) $ 8.09 $ (2.20) $ 8.08 Antidilutive common stock equivalents are excluded from the computation of diluted income (loss) per share.

Notes Receivable Notes receivable consists of the following principal and interest balances as of June 30, 2024 and December 31, 2023 (in thousands): June 30, 2024 December 31, 2023 Principal and interest Principal and interest TTG Note $ 7,821 $ 7,459 MDOS Note 1,042 1,192 KBS Customer Note 176 176 $ 9,039 $ 8,827 As a part of the TTG Transaction described further in Note 2. “Discontinued Operations,” we entered into a $7 million promissory note which represents an unsecured note receivable on our balance sheet. The note has a maturity date of May 3, 2029 with payment-in-kind (non-cash) interest on the outstanding principal balance hereof to accrue at the Interest Rate. The full balance is scheduled to be paid at the maturity date. The Interest Rate is defined as (i) during the period from the date of issuance of the note through the third anniversary of the date of issuance of the note, a per annum rate equal to the sum of (x) 5.0% per annum plus (y) the greater of 5.0% per annum and the weighted average term SOFR-based interest rate of outstanding loans under the Senior Loan Agreement (as defined in the Purchase Agreement) during such period, and (ii) during the period following the third anniversary of the date of issuance of the note, a per annum rate equal to the sum of (x) 5.0% per annum plus (y) the greater of 7.0% per annum and the weighted average term SOFR-based interest rate of outstanding loans under the Senior Loan Agreement during such period. In 2021 we completed the sale of MD Office Solutions in exchange for a secured promissory note (the “MDOS Note”). This note, the principal of which is approximately $1.0 million at June 30, 2024, is included in “Notes receivable, current portion” and “Notes receivable” in our Consolidated Balance Sheet at June 30, 2024 for $0.2 million and $0.8 million, respectively. The MDOS Note requires quarterly installments of $74 thousand and incurs interest at a fixed rate of 5.0% through maturity in 2028. In 2023, KBS issued a promissory note to a customer, incurring 12% interest per annum (the “KBS Customer Note”). The KBS Customer Note, which has a maturity date with full payment due of September 19, 2024, is included in “Notes receivable, current portion” in the Consolidated Balance Sheets at June 30, 2024. Cost Method Investment As a part of the sale of Digirad Health, we received $6.0 million in the common equity of TTG Parent LLC (our “Cost Method Investment”), which is held in our Investments Segment. We have elected the measurement alternative under ASC 321, Investments-Equity Securities . The measurement alternative election allows for equity securities that do not have readily determinable fair values to be recorded at cost, with adjustments for impairment and certain observable price changes reflected in earnings. Such securities are adjusted to fair value when an observable price change occurs or impairment is identified. As of June 30, 2024, we recorded an impairment to the Cost Method Investment in the amount of $1.3 million. We recorded this impairment as we considered the financial performance of TTG Parent LLC relative to the average earnings from comparable companies. This impairment is recorded as a part of selling, general and administrative expenses on the Consolidated Statement of Operations.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis The Financial Accounting Standards Board’s authoritative guidance for fair value measurements establishes a three-level hierarchy based upon the inputs to the valuation model of an asset or liability. Level 1 inputs are quoted prices in active markets for identical assets; Level 2 inputs are inputs other than quoted prices that are significant and observable; and Level 3 inputs are significant unobservable inputs to be used in situations where markets do not exist or are illiquid. The following table presents information about our financial assets that are measured at fair value on a recurring basis, and indicates the fair value hierarchy of the valuation techniques we utilize to determine such fair value at June 30, 2024 and December 31, 2023 (in thousands): Fair Value as of June 30, 2024 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 3,833 $ — $ — $ 3,833 Total $ 3,833 $ — $ — $ 3,833 Fair Value as of December 31, 2023 Level 1 Level 2 Level 3 Total Assets (Liabilities): Equity securities $ 4,838 $ — $ — $ 4,838 Lumber derivative contracts 19 — — 19 Total $ 4,857 $ — $ — $ 4,857 The investment in equity securities consists of common stock of publicly traded companies. The fair value of these securities is based on the closing prices observed on June 30, 2024 and December 31, 2023, respectively, and recorded in “Investments in equity securities” in the condensed Consolidated Balance Sheets. During the six months ended June 30, 2024 and 2023, we recorded an unrealized loss of $75 thousand and gain of $947 thousand, respectively, resulting from market fluctuations, recorded in other income (expense), net in the condensed Consolidated Statements of Operations. We may enter into lumber derivative contracts in order to protect our gross profit margins from fluctuations caused by lumber price volatility. Such contracts, which are generally entered into to protect the gross margins on our wall panel contracts at EdgeBuilder and Glenbrook Building Supply, Inc. (“Glenbrook” and referred to jointly with EdgeBuilder as “EBGL”), are recorded within current assets or liabilities in the condensed Consolidated Balance Sheets. For the six months ended June 30, 2024 and 2023, we recorded a net loss of $65 thousand and a net gain of $4 thousand, respectively, in the cost of goods sold Gains and losses from lumber derivative contracts are recorded in cost of goods sold of the condensed Consolidated Statements of Operations and included the following for the six months ended June 30, 2024 and 2023, respectively: June 30, 2024 June 30, 2023 Unrealized gain (loss) on lumber derivatives $ (19) $ 147 Realized gain (loss) on lumber derivatives (46) (143) Total gain (loss) on lumber derivatives $ (65) $ 4 Gains and losses from investments in equity securities are recorded in other income (expense) of the condensed Consolidated Statements of Operations and included the following for the six months ended June 30, 2024 and 2023, respectively: June 30, 2024 June 30, 2023 Unrealized gain (loss) on equity securities $ (75) $ 947 Realized gain (loss) on equity securities 34 — Total gain (loss) on equity securities $ (41) $ 947

Availability under the Premier Loan Agreement is based on a formula tied to the EBGL Borrowers’ eligible accounts receivable, inventory and equipment. Borrowings under the Premier Loan Agreement bear interest at the prime rate plus 0.75% (and a minimum interest rate of 6.75%), with interest payable monthly and the outstanding principal balance payable upon expiration of the term of the Premier Loan Agreement. The Premier Loan Agreement also provides for certain fees payable to Premier during its term. The initial term of the Premier Loan Agreement expires on December 5, 2024 but may be extended from time to time at the request of the EBGL Borrowers, subject to approval by Premier. The EBGL Borrowers’ obligations under the Premier Loan Agreement are guaranteed by the Company and secured by all of their inventory, equipment, accounts and other intangibles. As of June 30, 2024, availability under the Premier Loan Agreement was approximately $1.2 million. Financial covenants associated with the Premier Loan Agreement require that the EBGL Borrowers annually maintain (a) a debt service coverage ratio for any calendar year of less than 1.25; (b) a debt-to-equity ratio at the end of each calendar year in excess of 1.65; (c) a fixed charge coverage ratio at the end of each calendar year of less than 1.10; (d) working capital of at least $2 million; and (e) a current ratio of at least 1.50. As of December 31, 2023, the EBGL Borrowers were not in compliance with the annual Premier Loan Agreement covenants. The EBGL Borrowers have obtained a waiver from Premier for the annual covenant breach as of December 31, 2023. KeyBank Facility On April 24, 2024, KBS entered into a Loan and Security Agreement (the “KeyBank Loan Agreement”) with KeyBank National Association (“KeyBank”) providing KBS with a working capital line of credit of up to $4.0 million, subject to the conditions and procedures set forth in the KeyBank Loan Agreement. All borrowings under the KeyBank Loan Agreement bear interest at the Adjusted Daily SOFR Rate (as defined in the KeyBank Loan Agreement) plus 3%, with interest payable monthly and the outstanding principal balance payable on April 30, 2025 (the “Maturity Date”). The KeyBank Loan Agreement also provides for certain fees payable to KeyBank during its term. The initial term of the KeyBank Loan Agreement expires on the Maturity Date but may be extended from time to time at the request of KBS, subject to approval by KeyBank. KBS’ obligations under the KeyBank Loan Agreement are guaranteed by the Company and secured by all of KBS’ inventory, equipment, accounts and other intangibles, and all proceeds of the foregoing. Simultaneous with the execution of the KeyBank Loan Agreement, the Company entered into that certain Guaranty, dated April 24, 2024 (the “Guaranty”), pursuant to which the Company agreed to guarantee all amounts borrowed by KBS under the KeyBank Loan Agreement. Financial covenants require that KBS maintain a ratio of its Operating Cash Flow to its Total Fixed Charges of at least 1.25 to 1.0 measured quarterly for the preceding twelve month period, commencing with the fiscal quarter ending June 30, 2024, and for each subsequent fiscal quarter thereafter. As of June 30, 2024, we were not in compliance with these financial covenants and have not obtained a waiver of compliance as of the filing date. Our balance outstanding under the line amounted to $1.0 million at June 30, 2024 and we repaid the balance in full subsequent to quarter end. Failure to regain compliance or obtain a waiver may impact our ability to borrow on the line. Term Loan Secured by Mortgage On June 28, 2024, in connection with our acquisition of substantially all of the assets used in the business of Timber Technologies, Inc. which closed on May 17, 2024, Timber Properties, LLC (“Timber Properties”), an affiliate of the Seller, sold to 106 Bremer, LLC, a wholly-owned subsidiary of the Company (“106 Bremer”), all of Timber Properties’ Owned Real Property pursuant to a Real Estate Sales Agreement for $3.0 million plus closing costs. In connection with the purchase of the Owned Real Property, on June 28, 2024, 106 Bremer issued a Promissory Note in the principal amount of $3.0 million (the “TT Property Note”) secured by a Mortgage (the “TT Property Mortgage”) on the Owned Real Property to Timber Properties. All borrowings under the TT Property Note bear interest at 7.50%, with interest payable quarterly and the outstanding principal balance payable on June 29, 2034. Bridgewater Facility In connection with the completion of the TT Acquisition, on May 17, 2024, Timber Technologies Solutions, Inc., a wholly-owned subsidiary of the Company (the “Borrower”), entered into a Loan Agreement (the “Bridgewater Loan Agreement”) with Bridgewater Bank (“Bridgewater”) and issued a Term Promissory Note to Bridgewater in the amount of $7.0 million thereunder (the “Facility”). All borrowings under the Facility bear interest at 7.85%, with interest payable monthly and the outstanding principal balance payable on May 20, 2029 (the “Maturity Date”). The Bridgewater Loan Agreement also provides for certain fees payable to Bridgewater during its term, certain of which have been prepaid at closing. The Borrower’s obligations under the Facility are guaranteed by the Company and secured by all of the Borrower’s inventory, equipment, accounts and other intangibles, and all proceeds of the foregoing. In connection with the Bridgewater Loan agreement, an amount of $1.0 million was required to be deposited with Bridgewater and be under the sole dominion and control of Bridgewater, and the Company shall not have any control over the use of, or any right to withdraw any amount of the restricted deposit. In the event that the Company maintains compliance with all of the financial covenants set forth in the Bridgewater Loan Agreement for a certain period of time, Bridgewater shall release a portion of the deposit. The $1.0 million deposit is recorded in Other Assets Financial covenants require that TT maintain (i) a ratio of Cash Flow to Total Fixed Charges of not less than 1.30 to 1.00 as measured on each applicable Measurement Date on a trailing twelve (12) month basis; the first Measurement Date is September 30, 2024; (ii) maintain a ratio of Senior Funded Debt to trailing twelve (12) month Adjusted EBITDA not to exceed 3.00 to 1.00 as measured on each applicable Measurement Date for a Measurement Period; the first Measurement Date is June 30, 2025; (iii) maintain a ratio of Total Funded Debt to trailing twelve (12) month adjusted EBITDA not to exceed 4.00 to 1.00 as measured on each applicable Measurement Date for a Measurement Period; the first Measurement Date is June 30, 2025. Webster Credit Facility On March 29, 2019, the Company entered into a Loan and Security Agreement (the “Webster Loan Agreement”) by and among certain subsidiaries of the Company, as borrowers, the Company, as guarantor, and Sterling National Bank (“Sterling”). On February 1, 2022, Sterling became part of Webster Bank, N.A. (“Webster”), and Webster became the successor in interest to the Webster Loan Agreement. The Webster Loan Agreement was also subject to a limited guarantee by Mr. Eberwein, the Executive Chairman of our board of directors. The Webster Loan Agreement was a five-year credit facility maturing in March 2024, with a maximum credit amount of $20.0 million for revolving loans (the “Webster Credit Facility”). In connection with the sale of our Healthcare business on May 4, 2023, we paid all amounts due and closed the Webster Credit Facility. eCapital Credit Facilities The EBGL Borrowers were parties to a Loan and Security Agreement with eCapital Asset Based Lending Corp. (“eCapital”) providing for a $4.0 million credit facility with a maturity date of June 2023 and an auto-renewal of one year thereafter. KBS was a party to a Loan and Security Agreement with eCapital, providing up to $4.0 million in working capital, which was scheduled to mature and renew automatically for a period of one year moving forward. During the second quarter of 2023, we closed these two credit facilities and have no remaining debt balance with eCapital. eCapital Term Loan We and certain of our Investments subsidiaries were party to a Loan and Security Agreement with eCapital, as successor in interest to Gerber Finance, Inc., which provided for a credit facility with borrowing availability of up to $2.5 million, bearing interest at the prime rate plus 3.5% per annum, and maturing on January 31, 2025, unless terminated in accordance with the terms therein. During the second quarter of 2023, we closed this credit facility and have no remaining debt balance with eCapital.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, we have been and will likely continue to be subject to litigation or administrative proceedings incidental to our business, such as claims related to compliance with regulatory standards, customer disputes, employment practices, wage and hour disputes, product liability, professional liability, malpractice liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters but currently do not expect that the resolution of these matters will have a material adverse effect on our financial position or results of operations. The outcome of litigation and the amount or range of potential loss at particular points in time may be difficult to ascertain. Among other things, uncertainties can include how trial and appellate courts will apply the law and interpret facts, as well as the contractual and statutory obligations of other indemnifying and insuring parties. The estimated range of reasonably possible losses, and their effect on our financial position is based on currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We provide for income taxes under the asset and liability method. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between the tax basis of assets or liabilities and their carrying amounts in the financial statements. We provide a valuation allowance for deferred tax assets if it is more likely than not that these items will expire before we are able to realize their benefit. We calculate the valuation allowance in accordance with the authoritative guidance relating to income taxes, which requires an assessment of both positive and negative evidence regarding the realizability of these deferred tax assets, when measuring the need for a valuation allowance. Significant judgment is required in determining any valuation allowance against deferred tax assets. We continue to record a full valuation allowance against our deferred tax assets and intend to maintain a valuation allowance until sufficient positive evidence exists to support its reversal. Intraperiod tax allocation rules require us to allocate our provision for income taxes between continuing operations and other categories of comprehensive income, such as discontinued operations. For the three months ended June 30, 2024 and 2023, we recorded an income tax benefit of $39 thousand and an income tax expense of $61 thousand within continuing operations. We also recorded an income tax expense of $300 thousand within discontinued operations for the three months ended June 30, 2023. For the six months ended June 30, 2024 and 2023, we recorded an income tax benefit of $4 thousand and an income tax expense of $61 thousand within continuing operations. For the six months ended June 30, 2023 we also recorded an income tax expense of $300 thousand within discontinued operations. The tax benefit of $4 thousand for the six months ended June 30, 2024 and income tax benefit of $39 thousand relate to retroactive favorable state tax law changes which decreased our cash taxes for December 31, 2023. The tax expense for the six months ended June 30, 2023 primarily relates to our January 2022 ownership change under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), which required us to establish an additional valuation allowance on net operating losses that the Company cannot utilize in the future. As of June 30, 2024, we had unrecognized tax benefits of approximately $300 thousand related to uncertain tax positions. Included in the unrecognized tax benefits were $300 thousand of tax benefits that, if recognized, would reduce our annual effective tax rate, subject to the valuation allowance.

Segment Reporting [Abstract]
Segments	Segments Our reportable segments are based upon our internal organizational structure, the manner in which our operations are managed, the criteria used by our Chief Executive Officer, who is our Chief Operating Decision Maker (“CODM”), to evaluate segment performance, the availability of separate financial information, and overall materiality considerations. Effective as of the consummation of the sale of our Healthcare business on May 4, 2023, our business divisions are organized into the following two reportable segments, reflecting the manner in which our CODM assesses performance and allocates resources: 1. Building Solutions 2. Investments Prior to the sale of Digirad Health on May 4, 2023, we also had a Healthcare segment. Our reporting segments have been determined based on the nature of the products and services offered to customers or the nature of their function in the organization. We evaluate performance based on gross profit and operating income (loss). Our operating costs included in our shared service functions primarily consist of senior executive officers, finance, human resources, legal, and information technology. Star Equity shared service corporate costs have been separated from the reportable segments. Prior period presentation previously disclosed conforms to current year presentation.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Mergers and Acquisitions	Mergers and Acquisitions Timber Technologies Solutions On May 17, 2024, we acquired, through certain wholly owned subsidiaries, substantially all of the assets of Timber Technologies Inc. and, on June 28, 2024, the real assets of Timber Properties, LLC (collectively, “TT”) for total consideration of $23.1 million consisting of cash paid at closing of $19.1 million, $1.0 million of escrow funds included in accrued liabilities, plus a Term Loan Secured by a Mortgage of $3.0 million. The initial purchase price is subject to a standard working capital adjustment and other customary closing adjustments to be settled within 45 days post close. The Company is also subject to payments due to the sellers contingent upon the achievement of certain EBITDA metrics over a 2-year period and may result in total payments not to exceed $4.1 million, 50% of which is payable in cash and 50% of which is payable in Series A Preferred Stock. These payments are also contingent upon the continued employment of the individuals. The Company has concluded that these payments are akin to compensation and will be recorded if and as such compensation is earned. The Company has restricted $1.0 million of cash associated with the escrow funds payable to the sellers within 12 months after the acquisition as defined in the escrow agreement. In accordance with ASC 805, Business Combinations, we accounted for this transaction as a business combination and recorded the acquired assets of TT at fair value. The valuation of assets acquired and liabilities assumed has not yet been finalized as of June 30, 2024. The purchase price allocation is preliminary and subject to change, including the valuation of property and equipment, intangible assets, income taxes, and goodwill, among other items. The amounts recognized will be finalized as the information necessary to complete the analysis is obtained, but no later than one year after the acquisition date. Finalization of the valuation during the measurement period could result in a change in the amounts recorded for the acquisition date fair value. This business is reported as part of our Building Solutions segment. The following table sets forth the purchase price allocation of TT to the estimated fair value of assets acquired as of the acquisition date (in thousands): As of Acquisition Date Accounts receivable, net $ 766 Inventory, net 2,836 Other current assets 2 Property and equipment, net 7,156 Intangibles 8,900 Net assets acquired 19,660 Goodwill 3,440 Purchase price $ 23,100 The $8.9 million of identified intangible assets was allocated as follows (in thousands): Fair Value Useful Life Trade Names $ 1,970 15 Customer Relationships 6,640 10 Backlog 290 1 Fair value of identified intangible assets $ 8,900 Goodwill and intangibles of $3.4 million and $8.9 million, respectively, were assigned to the Building Solutions segment. The goodwill recognized is attributable primarily to expected synergies and the assembled workforce of TT. As of June 30, 2024, there were no changes in the recognized amounts of goodwill resulting from the acquisition of TT. The Company recognized $0.2 million of acquisition related costs including legal and accounting that were expensed in 2024. The following represents certain information from the unaudited pro forma condensed Consolidated Statement of Operations as if TT had been included in the consolidated results of the Company for the three and six months ending June 30, 2024 and 2023 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Revenue $ 18,145 $ 13,933 $ 31,296 $ 30,699 Gross profit 5,491 4,871 8,987 11,868 Net income (loss) from continuing operations, net of tax (2,065) 588 (2,943) 1,508 These amounts have been calculated after applying the Company’s accounting policies and adjusting the results of TT to reflect the additional depreciation and amortization that would have been charged assuming the fair value adjustments to property, plant, and equipment and intangible assets had been applied on January 1, 2024, together with the consequential tax effects. Big Lake Lumber On October 31, 2023, we acquired, through certain wholly owned subsidiaries, the assets and liabilities of Big Lake Lumber Inc. (“BLL”) for consideration consisting of cash of $2.8 million and an earn-out provision of up to $0.5 million. As a result of this transaction, EBGL expanded its market share of the Greater Minneapolis area. BLL’s operations were integrated into and became part of Glenbrook’s operations. The earn-out provision, which is accounted for as a contingent liability, is based on a specific gross profit threshold with a measurement period of two years to begin one year after the closing date of the acquisition and can potentially amount to up to $0.3 million for each of the two years, subject to certain limitations. The estimated fair value of the earn-out, which is determined using estimates of forecasted operations and other assumptions, was $0.2 million as of the acquisition date. No change to the fair value of the earn-out was recorded in Accrued Liabilities on our condensed consolidated balance sheet through June 30, 2024. In accordance with ASC 805, we accounted for this transaction as a business combination and recorded the assets and liabilities of BLL at fair value. The fair value of the net assets acquired amounted to approximately $4.1 million at the date of acquisition, and as a result, we recorded a gain of $1.2 million on our 2023 Consolidated Statement of Operations related to the excess of the fair value of the net assets acquired over the acquisition price. This excess is referred to as a “bargain purchase.” This bargain purchase indicates that the fair value of the net assets acquired (which represents the price at which the assets would be exchanged between a willing buyer and seller) was in excess of the amount for which we acquired such net assets. As a result of the bargain purchase, we reassessed the recognition and measurement of net identifiable assets acquired and determined the valuation procedures applied and resulting measurements of the net identifiable assets were appropriate. We believe the seller was motivated to complete the sale as part of its overall business strategy of exiting the market segment. The following table sets forth the purchase price allocation of BLL to the estimated fair value of assets acquired as of the acquisition date (in thousands): As of Acquisition date Purchase Price Cash Paid to Sellers $ 2,770 Fair Value of Earn-out Provision 169 Total consideration 2,939 Purchase Price allocation Inventories, net 438 Accounts receivable 578 Property and equipment 2,654 Intangible assets 900 Deferred tax liability (461) Fair value allocated to net assets acquired 4,109 Bargain purchase gain $ (1,170) The following represents certain information from the unaudited pro forma condensed Consolidated Statement of Operations as if BLL had been included in the consolidated results of the Company for the three and six months ending June 30, 2023 (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2023 2023 Revenue $ 11,842 $ 24,743 Gross profit (loss) 3,192 7,740 Net income (loss) from continuing operations, net of tax (1,103) (1,086)

Dividends are payable quarterly, in arrears, by the last calendar day of March, June, September and December to holders of record at the close of business on the first day of each payment month. The Series A Preferred Stock is not convertible and does not have any voting rights, except when dividends are in arrears for six or more consecutive quarters, then the holders of those shares together with holders of all other series of preferred stock equal in rank would be entitled to vote separately as a class for the election of two additional directors to board of directors, until all dividends accumulated on such shares of Series A Preferred Stock for the past dividend periods and the dividend for the current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof set apart for payment. The Company may redeem the Series A Preferred Stock upon the occurrence of a change of control, subject to certain conditions. The Company may also voluntarily redeem some or all of the Series A Preferred Stock on or after September 10, 2024. On February 16, 2024, our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $0.5 million. The record date for this dividend payment was March 1, 2024 and the payment date was March 11, 2024. On May 21, 2024, our board of directors declared a cash dividend to holders of our Series A Preferred Stock of $0.25 per share, for an aggregate amount of approximately $0.5 million. The record date for this dividend payment was June 1, 2024 and the payment date was June 11, 2024. As of June 30, 2024, we are current on our preferred dividend payments. On June 2, 2021, the board of directors adopted a tax benefit preservation plan in the form of a Section 382 Rights Agreement (the “382 Agreement”). The 382 Agreement is intended to diminish the risk that our ability to use our net operating loss carryforwards to reduce future federal income tax obligations may become substantially limited due to an “ownership change,” as defined in Section 382 of the Internal Revenue Code of 1986, as amended. The board of directors authorized and declared a dividend distribution of one right for each outstanding share of Common Stock to stockholders of record as of the close of business on June 14, 2021. Each right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series C Participating Preferred Stock, par value $0.0001 per share (the “Series C Preferred Stock”), at an exercise price of $12.00 per one one-thousandth of a share of Series C Preferred Stock, subject to adjustment. The rights will become exercisable following (i) 10 days after a public announcement that a person or group has become an Acquiring Person (as defined in the 382 Agreement); and (ii) 10 business days (or a later date determined by the board of directors) after a person or group begins a tender or an exchange offer that, if completed, would result in that person or group becoming an Acquiring Person. In addition, upon the occurrence of certain events, the exercise price of the rights would be adjusted and holders of the rights (other than rights owned by an acquiring person or group) would be entitled to purchase common stock at approximately half of market value. Given the potential adjustment of the exercise price of the rights, the rights could cause substantial dilution to a person or group that acquires 4.99% or more of common stock on terms not approved by the board of directors. As of June 2, 2024, the 382 Agreement has expired. No rights were exercisable at June 30, 2024. There is no impact to financial results as a result of the adoption of the 382 Agreement for the six months ended June 30, 2024.

The Amendment does not affect the par value of our common stock. The Reverse Split became effective on June 14, 2024, at 5:00 p.m. Eastern Time, at which time every five shares of the Company’s issued and outstanding common stock were automatically combined into one share of common stock..

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and disclosures made in the accompanying notes to the consolidated financial statements. Significant estimates and judgments include those related to revenue recognition, goodwill valuation, asset impairment, business combination accounting, and income taxes. Actual results could materially differ from those estimates.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. We limit our exposure to credit loss by generally placing cash in high credit quality financial institutions or in major money market mutual funds offered through brokerage firms. Some of our cash balances are maintained at major banking institutions in the United States, a portion of which may, from time to time, exceed the regulatory limit of $250,000 insured by the Federal Deposit Insurance Corporation (FDIC). We have not experienced any credit losses associated with our cash balances. Additionally, we have established guidelines regarding diversification of our investments and their maturities, which are designed to maintain principal and maximize liquidity. As of June 30, 2024, we had $0.7 million of cash in excess of FDIC insured limits.
New Accounting Standards To Be Adopted	New Accounting Standards To Be Adopted No new accounting standards were issued in the quarter ended June 30, 2024 that are expected to have a material impact on our financial statements.
Reclassifications	Reclassifications
Commitments and Contingencies	In the normal course of business, we have been and will likely continue to be subject to litigation or administrative proceedings incidental to our business, such as claims related to compliance with regulatory standards, customer disputes, employment practices, wage and hour disputes, product liability, professional liability, malpractice liability, commercial disputes, licensure restrictions or denials, and warranty or patent infringement. Responding to litigation or administrative proceedings, regardless of whether they have merit, can be expensive and disruptive to normal business operations. We are not able to predict the timing or outcome of these matters but currently do not expect that the resolution of these matters will have a material adverse effect on our financial position or results of operations. The outcome of litigation and the amount or range of potential loss at particular points in time may be difficult to ascertain. Among other things, uncertainties can include how trial and appellate courts will apply the law and interpret facts, as well as the contractual and statutory obligations of other indemnifying and insuring parties. The estimated range of reasonably possible losses, and their effect on our financial position is based on currently available information and is subject to significant judgment and a variety of assumptions, as well as known and unknown uncertainties.
